Abstract
In an apparatus on a drafting system of a spinning room machine, especially a draw frame, carding machine, combing machine or the like, for weighting the drafting system rollers, at least one pressure-medium cylinder with a piston is acted upon by pressure medium and is arranged so as to be axially movable inside a cylinder housing. A piston rod extends from piston passing through at least one cylinder cover that defines the cylinder housing at the end. In order to improve the apparatus, for determining the position of the piston with the piston rod, at least one inductive displacement sensor is integrated into the pressure-medium system, and the inductive displacement sensor is connected to an evaluation device.
Description
Technical field
The present invention relates to the equipment on the drafting system in a kind of spinning machinery, described spinning machinery is drawing frame, carding machine, combing machine etc. especially, this equipment is used for counter extensioin device roller and loads, it has at least one pressure medium cylinder of being furnished with piston, piston works by pressure medium, and be arranged to and in cylinder housing, move axially, one piston rod extends from piston, piston rod passes at least one cylinder cap that limits cylinder housing endways, wherein, be provided with an inductive pick-up device that is used for determining piston position by piston rod.
Background technology
In known equipment (EP 1 428 914 A), changeover panel by friction installation coaxially, can move it with piston on piston rod, and this changeover panel is cooperated with switch to determine position of piston.For with cooperate as the inductive pick-up of switch to determine piston position, changeover panel to small part is a permanent magnetism.If form a circle fibrous material around top roller, then the top roller of Fu Donging will be pressed to the direction of pressure medium cylinder.Thereby the depression bar of the pressure medium cylinder that comes in contact with top roller moves along the end position of its withdrawal.When depression bar was withdrawn, the changeover panel mounted thereto that rubs was connected with switch, and drafting system is turned off.Then, can the manual unlocking drafting system, remove that circle fibrous material.Then, by closing loading arm, drafting system just enters operating position once more.In known equipment, by induction near switch, can realize that piston is the very detection of ad-hoc location (reel monitoring lap monitoring).Such inductive pick-up has a moving together contact, when piston when the predetermined position, this contact closure, and correspondingly send the monitoring flaw indication of reeling to control device.After top roller bottoming arrangement, all must redeterminate this position at every turn.Another significant disadvantage is exactly to detect the stroke (up and down) of piston.
Summary of the invention
Technical problem to be solved by this invention is exactly further to improve with piston rod to determine equipment on the drafting system of piston position.
In order to solve the problems of the technologies described above, the invention provides the equipment on the drafting system in a kind of spinning mechanism, this equipment is used for counter extensioin device roller and loads, it has at least one pressure medium cylinder of being furnished with piston, pressure medium acts on the piston, and described piston is arranged to and can be moved axially in cylinder housing, one piston rod extends from piston, this piston rod passes at least one cylinder cap that limits cylinder housing endways, wherein, be provided with at least one inductive displacement pick-up that is used for determining piston position by piston rod, it is characterized in that, determine position of piston in order to use piston rod, at least one inductive displacement pick-up is incorporated in the pressure medium system of being made up of the piston of cylinder housing and available pressure media for activation, and, described inductive displacement pick-up is connected with an electronic evaluating device, inductive displacement pick-up comprises plunger core body and plunger coil, plunger core body is movably, and the plunger coil is on the fixing position, plunger core body is connected with piston, and the plunger coil is connected with the inwall of cylinder housing.
Equipment according to the present invention makes it can pass through inductive displacement pick-up, uses control technology to monitor the piston motion of both direction up and down that comprises platform.The result that piston is advanced at both direction is exactly, and the position of plunger core body in the plunger coil changes, thus the output signal that changes to control device conversely.Because output signal changes, control device can be distinguished piston moving on both direction.In addition, control device can be determined the route that piston is advanced by signal.By the measurement of precision, and the maximum by upwards being offset by the caused top roller of circumvolution (lap formation), can accurately discern " circumvolution " fault, wherein said value is stored in the control device.Therefore, can freely programme to providing the value that upwards is offset before the failure message, and can change this value as required.Another advantage of this range determination is exactly by adopting the control device of inductive displacement pick-up, can automatically realize the circumvolution and both accurate identification of wearing and tearing of top roller.The top roller of drafting system is furnished with resilient sleeve usually, for example the cover layer made such as rubber.When machining for the first time with new top roller, drafting system is closed, and works by compressed air.Inductive displacement pick-up is determined position of piston, and numerical value is stored in the control device.Use the numerical value of determining to calculate the roller diameter of new top roller, deduct greatest wear value (being stored in the control device) afterwards, just can obtain minimum roller diameter as preset parameter or variable element from this diameter.Similarly, also the roller diameter of minimum is stored.It is bigger that the wearing and tearing of top roller and the result of friction are exactly that spacing becomes.By inductive displacement pick-up being calibrated, all redefine the position in each when operation of closing drafting system at every turn.Up-to-date definite value has formed the current diameter of top roller.Control device compares current definite diameter with the program parameters of the wearing and tearing of fixing or the storage values of top roller minimum diameter.When top roller has reached minimum roller diameter, machine just is transformed into fault mode and shutoff.Top roller must be replaced with new roller.Have only when distance measurement shows roller diameter greater than predetermined minimum roller diameter, machine just can rerun.According to the present invention, the displacement measurement in the pressure arm has been realized the measurement of not having wearing and tearing and haveing nothing to do with tolerance on the both direction of piston, and this measurement is absolute accurate, can also monitor the circumvolution and the wearing and tearing of top roller automatically.If necessary, in order to add up, can recover all storage values relevant with abrasion condition again from control device with the circumvolution of top roller.Machine fail to start under the situation that top roller is ground away.Therefore, can not be owing to the top roller of grinding away causes spillage of material.A special advantage is that inductive displacement pick-up is integrated in the pressure medium system, has reached the effect of significant designs simplification, and plunger core body is connected with piston, and the plunger coil is connected with the inwall of cylinder housing.
